This is a Linage, meaning you adapt an existing race to these stats
Ageless: You don't age, and effects that would cause you to age don't work on you.
Cling to Life: when you make a death saving throw and roll a 16 or higher, you regain 1 hp.
Revenance: You retain your creature type yet you register as undead to spells and other effects that detect the presence of the undead creature type.
Unsettling Presence: As an action you can unsettle a creature you can see within 15 feet of you. The target has disadvantage on the next saving throw it makes within the nex tminute. Constructs, undead, and creatures that can't be frightened are immune to this feature. Once you use this feature , you can't use it again until you finish a long rest.
Cold Iron Vulnerability: You suffer the weakness of the fey that gave you your unlife.
Your culture is based off who you were in life.
